New partition stud walls

We are converting the loft in our house and have put a new floor in place and new rafters etc. Currently we have a large open space which needs dividing up with partition walls.

Do the partition stud walls get errected before the ceiling is boarded - or do we first plasterboard the ceiling - or doesn't it matter ??

Thanks for any advice.

Doesn't matter, might as well do it first though. Easier to locate joists/studs/rafters.
No it doesn't matter, there are pros and cons either way.
Makes that you plasterboard the ceiling in 12.5mm board and not 9.5mm.
This will help prevent the boards from sagging and hopefully will not crack plaster on the joints in later years.

Whenever we need to partition a room with stud walls we fit the ceiling plasterboards (only directly above the stud walls) so that there aren't any problems with having to noggin out as to catch plasterboard ends.

The reason we only fit the boards where the stud wall is going is to leave access for other trades such as the sparky and plumber.

It sounds weird but it does save time. We also stagger the boards too. ;)
we organise all trades to fit in and we always board the ceilings first,making note of noggin should have double joists under your stud walls that run in line with the joists.these need bolting together so if you havent already done so,you may have problems doing it should also have noggins across the joists to supprot walls perpendicular to the joists.dont for get you will need insulation between your rafters and underneath before boarding.
Thanks for all the advice.

Think I'll just board the ceiling first where the walls will be to start with - that'll leave access for the electrics etc.

I think a continuous 12.5 plasterboard ceiling must give some advantages with fire regs etc.
why not get the sparky in first and then just board all the ceilings,erect stud wall and then poke sparkies wires through the plasterboard as you board,simple.
